You can count on reliable Opto 22 I/OYou’ve known Opto 22 for over 30 years as the manufacturer of high-quality SSRs. Do you know we make equally reliable I/O? Worldwide, over 85 million devices are connected to Opto 22 systems. Here’s why you can count on Opto 22 I/O:Quality. We test each I/O module twice before it leaves our factory in Temecula, CA. We make sure it works before we ship it to you.Warranty. Most I/O modules are guaranteed for life.Variety. We offer a broad range of signal types, so you can find all the I/O you need for your application. Choose from all of these, plus more:
Digital, analog, and serial modules
AC, DC, dry contact, TPO, and quadrature
Current, voltage, temperature, rate, RMS, and pH/ORP
RS-232, RS-485/422, Profibus, and Wiegand
Isolation. Optical isolation protects sensitive control electronics from industrial field signals; transformer isolation on analog modules minimizes noise that may produce erroneous readings.Experience. We’ve been designing and building I/O since 1978. Our designs—for example, the red/black/yellow/white color coding—have become industry standards.Availability. Purchase through our worldwide network of distributors, online, or directly from us. Virtually all parts are in stock and ready to ship without delay.FREE product support. All Opto 22 products include free technical support for the life of the product. Product support is available by phone or email Monday through Friday, 7:00 a.m. to 5:00 p.m. Pacific Time.SNAP I/O and the SNAP PAC SystemSNAP I/O modules are part of the SNAP PAC System, a system of integrated hardware and software designed to simplify the typically complex task of understanding, selecting, buying, and applying automation systems. The SNAP PAC System includes PAC Project software, SNAP PAC controllers and brains, and SNAP I/O.SNAP I/O. Each I/O module contains from 1 to 32 input or output points, which you wire to sensors, actuators, and similar devices to monitor or control them. Virtually any electrical, electronic, or mechanical device can be wired to an Opto 22 I/O module.
Analog I/O modules handle devices that have a range of possible values. Temperature inputs and proportional valves are examples of analog devices.
Digital I/O modules handle devices that can be in only one of two states: either on or off (true or false, 0 or 1, running or stopped, etc.). Push buttons and LEDs are examples of digital devices.
Serial communication modules connect to serial devices using RS-232, RS-485/422, Profibus®, or the Wiegand® protocol.
Special-purpose modules are available for motion control, power monitoring, and other uses.
SNAP PAC brains are I/O processors that provide network communications and local intelligence (distributed control) for the I/O points. Brains perform basic control functions such as on/off control, counting, and latching, as well as complex tasks such as PID control and temperature conversion. Brains communicate using Ethernet protocols such as TCP/IP, UDP/IP, Modbus/TCP, SNMP, SMTP, OptoMMP, and EtherNet/IP. SNAP PAC brains and SNAP I/O modules mount on SNAP PAC racks, which provide support and connections. Racks can be panel mounted or DIN-rail mounted. Racks come in four sizes; as many as 512 points can be placed on one rack and controlled by one brain.
